The official zip code is the 5 digit, the -xxxx is a 4 digit extension referred to as zip+4. You can think of it as narrowing down the zip code to the neighborhood level, making it easier for the post office to properly process and route mail in the most efficient way. There are no 2 letter codes on zip codes. That is just someone's typo. So for example, Stockton, CA 95207, the CA is not a part of the zip code, is the state/province section of the address. Hope this helped. -- [EMAIL PROTECTED] <[EMAIL PROTECTED]>
